Content filtering is really easy to use. We have rules for content filtering. One of the rules that we have is that if it is not an SSL site, it should block the site. It scans, and if it finds a bad site, it is not going to allow it. We can also block based on what the company wants us to block. If the company wants us to block porn, we'll block porn. If the company wants to block social media, we're going to block social media.
